What plumbing & water projects cost in materials
Materials run $150 to $2,500 across 8 projects. The bottom is repair and pipe work: plumbing pipe installation or replacement at $150 to $850, sprinkler repair and maintenance at $150 to $850, and sump pump repair at $150 to $800. The top is anything you have to trench for: sprinkler and irrigation system installation at $500 to $2,500, drainage installation at $800 to $2,500, and french drain installation at $800 to $2,500. All materials only.
Where the DIY line sits
All 8 projects rate Intermediate. Nothing here is Beginner and nothing is Advanced, and that is honest. No job involving pressurized water or a buried run is a casual first project, because the failure mode is water where you cannot see it. Everything on this list needs you to know where the shutoff is, how to make a joint that does not weep, and how to test before you close a wall or backfill a trench. Call for utility locates before any digging.
What moves the price
Trench length and depth drive the top of this category more than anything else. Pipe material and diameter come next: PEX, copper, PVC, and corrugated pipe are not close per foot, and fittings multiply with every turn. For irrigation, zone count and head count set both pipe and valve costs. Gravel, filter fabric, and catch basins push french drains up. Soil type and rock decide how hard the digging goes.
Frequently asked questions
How much does a french drain cost in materials to DIY?
French drain installation estimates at $800 to $2,500 in materials: perforated pipe, washed gravel, filter fabric, fittings, and a discharge outlet. Drainage installation lands in the same $800 to $2,500 band. Trench length and depth drive the number, and gravel volume is the line item that grows fastest. Call 811 for utility locates before you dig.
Can I replace my own plumbing pipe?
Plumbing pipe installation or replacement estimates at $150 to $850 in materials and rates Intermediate, like every project in this category. A visible run in a basement or crawl space with a clean shutoff is reasonable DIY. Anything behind finished walls, tied to a water heater, or under slab is a different job. NailIt does not estimate gas lines at all, so gas piping goes to a licensed pro.
What does a DIY sprinkler system cost in materials?
Sprinkler and irrigation system installation estimates at $500 to $2,500 in materials, covering pipe, heads, valves, a manifold, a controller, and wire. Zone count is the main driver, since each zone adds a valve, more pipe, and more heads. Repair and maintenance on an existing system is much smaller at $150 to $850. Check local backflow prevention requirements before you tie into the supply.
